C. Shield Volcano.. think of Hawaiian volcanoes,they are basaltic eruptions, very effusive and unexplosive and are characterised by slow lava movement and very little tephra from the eruption. The basalt erupted is very hard, dense rock and so can be built up easily.
Answer:
3/16
Explanation:
Two true-breeding stocks of pea plants are crossed. One parent has red RR, axial flowers AA and the other has white rr, terminal flowers aa
Parent cross RRAA x rraa
Gamete: RA x ra
F1 gen. RrAa
Selfing of F1. RrAa x RrAa
F2 offspring
Rr x Rr Aa x Aa
RR Rr rr AA Aa aa
3/4 red 1/4 white 3/4 axial 1/4terminal
Probability of plants with white axial flowers is 1/4*3/4 = 3/16
Answer:
D. Increased sunlight and increased nutrients will increase phytoplankton populations.
Explanation:
Both sunlight and nutrients are required by phytoplankton communities. We know that <u>phytoplanktons</u> are <u>primary producers</u> and they produce food via <u>photosynthetic activities</u>. To carry out photosynthesis, <u>presence of (inorganic) nutrients and sunlight is highly important</u>. In this process, energy is fixed in energy rich molecules such as glucose and organism multiply and/or gain biomass. A decrease in any of them will result into reduced photosynthesis and hence reduced phytoplankton population growth.
